'Arrow' Season 2, episode 16: Is Harley Quinn in the 'Suicide Squad'?

"Arrow" fans are understandably excited about the upcoming "Suicide Squad" episode. But some have gotten even more excited about a character who may or may not be in the episode: Harley Quinn.

No one at "Arrow" has been willing to confirm or deny whether the "Batman" villain is in the episode, but a brief image in some of the trailers for "Suicide Squad" hint that she might make an appearance.

At about the 0:07 mark in the video, a brief shot reveals a female prisoner, her back turned to the camera. Wearing an A.R.G.U.S. jumpsuit and sporting two rather messy pigtails, DC comics fans have been quick to point out that this woman does indeed resemble the Harley Quinn character.

Is it really her? Will this woman be a major part of "Suicide Squad" or is she just a tease for something coming later? Decide for yourself when the "Arrow" episode airs Wednesday, March 19 at 8 p.m. on The CW.
